Cookie Free Domains and CDNs

After I dropped Cloudflare I went back looking at other ways to speed up my site and what could I optimize things. As I mentioned in Static Content Subdomain, one of the benefits of that mess was to allow me to have a cookie free domain and, in having a cookie free domain, I basically made a domain that could be used as a CDN for my (mostly) static files.

It was noted then that, if you’re a non-www person, you have to actually use a separate domain. I do. I hate www in URLs. So I picked up a free domain for the site where I’m doing all this: ex-static.com. I probably could have gotten it even shorter if I’d tried sitecdn.net but that was short enough for me.

Since I already had everything over at /home/user/public_html/static I created an add-on domain in cPanel and told it to use that as its home.

Then I ran a search/replace on WordPress:wp search-replace static.example.com/wordpress ex-static.com/wp-content/uploads
wp option set upload_path /home/example/public_html/static/wp-content/uploads

Since I’d already changed my media settings, that was all I needed to really run a replace. It changed my media settings too! Since I was planning to move my static content, not just images, I changed the path too, so I had to go back and change upload_path as well, but wp-cli is my friend.

Next up, because of the static content move, I copied my wp-content folder over and added this to my wp-config.php:

Sadly, it got messy for MediaWiki and ZenPhoto. The later doesn’t allow you to move your themes folder at all so I made a symlink to /home/example/public_html/static/themes/themename/ and called that a day. MediaWiki was a damn dirty lie.

Everything works as expected. And? I have cookie free domains and I’m ready to move all my data off to a CDN whenever I’m ready for that step. The CDN would only have to cover the ex-static.com domain, to boot!
